The
Australian plug/power outlet system is described in the SAA document AS
3112-2000 and is also used in New Zealand and Papua New Guinea.The
Australian plugs have three flat pins arranged offset and are
polarized. The connecting lead has to comply with the special SAA
regulations and has to be marked with the approval number N/... (e.g.
H05VV-F-3G1 N/...). For special mechanical stress, a „Heavy
Duty“ lead with a reinforced jacket is used.

There
are three plug systems, which differentiate from each other as follows:

7.5
A (up to 0.75 mm²) or 10 A / 250 V (1.0
mm²)All three contact pins have the same dimensions.
